EPsychology professor at Duke University, Joseph Banks Rhine was stubbornly determined to find out if extrasensory abilities were genuine or just some coincidence. In a joint study with his colleague Karl Zener they developed a card game with the purpose of practicing mental exercises. This game consisted of a deck of 25 cards divided in 5 series of 5 different simple and easily identifiable symbols.
Even though at the beginning it was very difficult to get positive results, after some time, Rhine came up with results that even the most skeptic people had to accept as something beyond coincidence.

On the right you'll see the chart with the best averages of the users of "the Realms of the Arcane". Take this perception test but remember that anybody can have at some point an extrasensory perception experience without this implying that they are telepathic or clairvoyant.
